Days. When a charterparty provides for laytime to be fixed or calculable this can be referred to a number of "days". The number of days is sometimes called "laydays" but this term is better used for the "Laydays and Cancelling" clause.
Document of title. In modern international trade and shipping this is probably the most important characteristic of the bill of lading. A "document of title" is a document that enables the holder (the person who "possesses" it) to deal with the goods described in it as if he was the owner. "Title" is the right to ownership. "Ownership" can be explained as the right of using, altering, disposing of (that is, selling) and destroying the goods. This "ownership" or "title" can be transferred by a formal transfer of the document, such transfer being an "endorsement" and/or delivery of the document itself.
Depth. The depth is the vertical distance measured from the keel to the deck. The extreme depth is the depth measured at the ship’s side from the uppermost continuous deck to the lower point of the keel. The moulded depth is measured from the top of the keel plate (the “base line”) to the underside (that is, the heel) of the deck beam at the ship’s side amidships.
Days on demurrage. These are days by which the agreed number of laydays for loading or discharge is exceeded. In some charters a limited fixed number of days on demurrage is agreed, in addition to the laytime allowed. Shipowners are entitled to damages for detention if, after demurrage days have expired, further delay is experienced.
